` IMPROVEMENT IN REGISTER FOR SPINNING-JACKE.

The Schedule referred to in. these Letters Patent and making part of the same.

-rn. d

To all persons to whom these presents may come:

Be it known that I, HENRY GREENWOOD, a citizen of England, for the present residing at Gilbertsvillc, in the county of XVorceSter, and State ot'- Massachusetts, have invented a new and useful Machine or Apl aratus for Measuring or Indicatin(y the Draws or p a o Out-Movements.of the Carriage of the Spinning- Machine, usually termed a jack; and I do hereby declare the same to be fully described in the following specification, and represented in the accompany-- ing drawings, of which- Figure l is a. front elevation of the registering-apparatus as it appears with the cover or front plate of its case removed from the rest of the sid case.

Figure 2 is a transverse section,

Figure 3, a longitudinal section, and

Figure 4, a side elevation of thesame, the connec tion of the apparatus with one of the delivery-rollers of the jack being represented in such iig. 4, and also iu fig. 1.

'lhe object of the invention is to prevent a spinner from pumping the clock or registering-apparat-us, or so moving it as t-o cause it to Vindicate a greater amount;

-of work than that actually performed.

The apparatus measures, by'means of the deliveryrollers, and a, registeriiig-mechanism, the number of draws or out-movements of the jack-carriage, thereby showing, from time to time, what spinners term the number of beer-s, runs, or cuts of yarn.

There are attached to Vthe appzu'atus a dia-l, B, and an indcxpointer, C, such being to indicate thelength of delivery of roving for each draw or out-movement ofthe carriage.

In the drawings, one of the delivery-rollers of the jack isshowu at A, with its. shaft or journal provided with a worm or lendless screw, a, to engage with and impart rotary motion to a worm-gear, b, fixed on the driving-shaft c ot' the registeri11g-apparatus.

'lhe dial B is fastened to or formed ou the side of the case D of the register', the index-pointer@` being fixed on the shaft c.

There is also fixed ou the'shaft c, a pawl-olutch, E, which is a wheel provided with aseries of apertures -d extending through it t-rausyersely, and arranged in a circular path, and at equal distances apart, the same being as shown in fig. 2.

Each ofthc passages l is formed with a flaring or trumpet-mouth at its inner cud, as shown in tig. 3. This clutch is to receive the pawl F, which is a pointed cylinder or pin projected from a. pendulous weight, G, suspended from and sous to be capable of swinging or turning ou the shaft c, and of being slid lengthwise thereon. v

A yoke, H, encompasses a grooved neck, e, ex-

tended froxn the weight G,such yoke being-jointed to a rod, f, extending through the next adiaceut side of the case.

-We are to suppose a pendulum or weighted lever to be suspended from an ear, g, projecting from the case, and such pendulum to be jointed to the rodf, and arranged in such manner that while the carriage is being put in gear, the pendulum or weighted lever will be swung bac-k, so as to cause the weight G to be moved ina manner to draw the pawl F entirely out ofthe clutch E.

.As soon as the paw] F is dra-wu out of the clutch E, the gravitating pawl-carrier or weight G will fall down to its lowest position, so as to return the pawl to the proper situation for being again engaged with the clutch.

The said engagement will take place at the commencement ofthe out-movement' of the jack-carriage when the pendulum or weighted lever willV return to a Vertical position, and thereby engage the clutch. v

The pawl will be revolved by and with the shaft c, and will be caused to be engaged wit-h the toothed wheel I, fixed on another or worm-shaft K, and to move said wheel one tooth forward, to indicate the ynumber of draws or out-movements of the carriage.

A spriugretaiuiug pawl, L, acts against the wheel I, or is arranged therewith in manner as shown in thev drawings. l

Furthermore, a worm or endless screw, M, fixed on the shaft K, engages with a worm-gearor rotary wheel N arranged to. revolve ou and being concentric with a. stationary arbor, l.

Au index-pointer, Q, fixed to the arbor P, serves t0 denote, with the scale of divisions found ou the face ofthe plate or wheel N, the extent of rotary motion of such wheel produced by the wheel while in ievolution.

The index-wheel N serves to indicate the numberl 0f draws otA the jack-carriage or amount of yarn spun, and such wheel will be put in motion only while the pawl F may be iu revolution by the clutch E.

lVere it not for the gravitatiug weight or pawl-carrier to operatev as described, the i'registering-apparatus would not indiette the correct number of draws, as the toothed wheel L would be lia-ble to be occasionally moved twice, rather than once only for each draw.

I claim as my invention, the following, viz:

The combination and arrangement ofthe pawl-clutch E and the gravitat-ing and sliding weight G, with the driving-shaft c, the pawl F, and the draw-registering mechanism operated thereby, substz'intinll y as described.

HENRY GREEN WOOD.
